Howto: Switching from Sun-Java5 to Sun-Java6 in Ubuntu6.10 (edgy)

Sun-Java6 has arrived in the backport repository of Ubuntu and this howto assumes you have this repository set up.

Install it to make it work in Firefox:

sudo apt-get install sun-java6-plugin
during install accept the licence ….continuing…

If you want the jdk package:

sudo apt-get install sun-java6-jdk

To set up sun-java6:

sudo update-alternatives –config java

This is what you see:

There are 3 alternatives which provide `java’.

      Selection    Alternative

-----------------------------------------------

1    /usr/bin/gij-wrapper-4.1

*         2    /usr/lib/jvm/java-1.5.0-sun/jre/bin/java

+        3    /usr/lib/jvm/java-6-sun/jre/bin/java

Press enter to keep the default[*], or type selection number:

In my case I have to select “3” and hit enter .

Thats it , you have Sun-Java6 up and running in the easiest way possible. 🙂

To revert back to sun-java5 for whatever reason :

sudo update-alternatives –config java

and select your preferred java-version.
